JOSEPH E. BARR/ANGER, 0F PHILADELPHIA, PENNSYLVANIA.

STEAM- GENERATOR.

To all whom it may concern: Be it known that I, Josnrrr E. BARRAN-= can, a citizen of the United States, resid- I ing in the city and county ofPhiladelphia, State of Pennsylvania, have invented a new; and useful Steam-Generator, of which the following is a specification.

My invention relates to a steam generator and consists of a device for heating feed water for a boiler by the action of exhaust steam from an engine or other source, then subjecting the resultant saturated steam to the heat of a gas retort, thus producing partially dry steam, and lastly directing said steam into a boiler whereby the steam is produced fully dry and live, means being also employed for utilizing the gas of said retort as a fuel for the furnace of said boiler.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific arrangement and organization shown and described.

The figure represents a longitudinal vertical section of a steam generator embodying my invention.

Referring to the drawings: 1 designates a tank forreceiving and containing feed watcr for a steam boiler, the same inclosing the pipe 2 of the form of a coil one end of which is connected with the pipe 3 which leads from the exhaust of a steam engine or other source, and its other end is connected with the discharge 4 for the water of con densation of said coil. Connected with said tank is the pipe 5 which extends from the pump 6 and communicates therewith for supplying the tank with water which as is evident will be heated by the coil 2.

7 designates a pipe which is connected with and extends from the tank and joins the coil 8 in the retort 9, the interior of which latter is provided with the grate 10 for supporting fuel such as gas coal, which when ignited will highly heat the coil 8, the resultant gas also being adapted to enter the pipe 11 which is connected with the up per portion of said tank and has connected with it the elbow pipe 12, the lower end whereof is provided with the nozzle 13 which enters the injector or atomizer 1 1 from which extends the pipe 15, the latter Specification of Letters Patent.

Application filed March 3, 1913. Serial No. 751,843.

the injector 14- so nections form being in communication with the burner 16 Patented July 14, 1914.

whose location is within the furnace 17 of the steam boiler 18, said burner being composed of a series of pipes having jets or perforations for the outlet of gas admitted to the burner as will be hereinafter more fully referred to. i

19 designates a pipe which is connected with the steam space of the boiler and with as to direct steam into the latter, the steam uniting with the gas admitted into the injector by the nozzle 13, the result combining steam and gas forming a liquid fuel which supplies the burner 16 and which when ignited at thejets thereof highly heats the boiler 18.

Itwill be seen that the water in the tank 1 is 0011 8 whereby it is converted into saturated steam, the latter then entering the boiler through the pipe 25 whereby it becomes fully dry live steam. It will be seen also that the gas from the retort 9 is not lost in aflue or stack but utilized in connection with steam admitted to the injector 14 as the medium for heating the boiler as has been stated, it being noticed that the retort has a draft inlet 20, and the pipe'll and its con- .rdraft outlets or fines for maintaining combustion in the retort, and the escape of the products thereof. The retort has a supply chute or inlet 21 preferably on the top thereof.

In the pipes 25, 7 and 19 are checkvalves 22, 23 and 24- respectively for evident purposes.

It will be understood from the foregoing, that the retort or gas producer 9 may be of any conventional type, the fuel being introduced through the opening'21 in the to thereof, in case coal is employed, or, if desired, gas can be employed in lieu of the fuel on the grate bars 10. By conducting the waste gases or products of combustion from the interior of the gas producer 9 through the pipe 12, and commingling the same with dry steam from the boiler, through the medium of the pipe 19, I produce an eflicient heating medium for the boiler 18 and am enabled to dispense with the usual grate bars or the use of coal, or similar fuel to heat said boiler 18, the result being that the products of combustion or gases from the gas producer 9, which would ordinarily be wasted, are, after commingling with steam conducted through the pipe 19 to the injector 14 utilized as a heating superheated by the coil 2, and entersthe" medium for the boiler 18, it being apparent that the saturated steam from the coil 8 may be conducted through the pipe either into the water space of the boiler 1801' into the steam space thereof, or both, as may be desired.

By the employment of the checkvalves, 23, 24c and 22 located in their respective pipes, I am enabled to prevent any improper backing up of the pressures of the fluids therein, and it Will be understood that I mayvemploy straight tubes instead of the coil 8 if desired, and in lieu of the fire tube boiler 18, I may employ a water tube boiler, if desired.

I have deemed it unneccessary to show the check valves or the injector in detail, as any conventional type may be employed and their construction and manner of operation Will be apparent to those skilled in this art.

It vvill be seen that the water receivingcoil 8 iscontained directly in the body of the retort 9. This simplifies the construction of the gas-producing and steam-generating device in' that an exterior Water receiving jacket for the body of the retort is avoided and the coil. 8 is subjected to the direct action of the products of combustion around and through the same.

Having thus described my invention What I claim as new and desire to secure by Letters Patent, is A gas generating retort, a generator for saturated steam therein, means for connecting said generator with a feed Water sup ply, a gas out-let and conveying pipe con nected With said retort, a steam out-let and conveying pipe connected with said generator, a boiler for generating live steam, a burner in the fire place of said boiler, and an atomizer connected with said burner, said gasoutlet' and conveying pipe having a connection with said atomizer, and said steam outlet and conveying pipe having a connection with the Water spaceof said boiler.
